Detailed Description

SLIP Interface

Macro Definition Documentation

◆ SLIP_MAX_SIZE

#define SLIP_MAX_SIZE 1500

Maximum packet size that is received by this netif

◆ SLIP_SIO_SPEED

#define SLIP_SIO_SPEED ( sio_fd ) 0

Define this to the interface speed for SNMP (sio_fd is the sio_fd_t returned by sio_open). The default value of zero means 'unknown'.

Function Documentation

◆ slipif_init()

err_t slipif_init ( struct netif * netif )

SLIP netif initialization

Call the arch specific sio_open and remember the opened device in the state field of the netif.

Parameters

netif the lwip network interface structure for this slipif

Returns: ERR_OK if serial line could be opened, ERR_MEM if no memory could be allocated, ERR_IF is serial line couldn't be opened

Note: netif->num must contain the number of the serial port to open (0 by default). If netif->state is != NULL, it is interpreted as an u8_t pointer pointing to the serial port number instead of netif->num.

◆ slipif_poll()

void slipif_poll ( struct netif * netif )

Polls the serial device and feeds the IP layer with incoming packets.
